SPRING-BOTTOM.

vSpecification of Letters Patent.

Patented sept. 19, 1905.

T0 @ZZ wir/011e it' may concer-71,:

Be it known that I, OznLLo R. HUNT, a citizen of the United States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented a new and useful Spring- Bottom, of which the following is a specification.

My invention pertains particularly to spring-bottoms for beds; and my primary object is to provide a bottom with improved.

means for supporting the fabric.

My invention is illustrated in its preferred embodiment in the accompanying drawings, in which4 Figure 1 represents a broken bottom plan view of my improved spring bed-bottom; Fig. 2, an enlarged broken section taken as indicated at line 2 of Figzml; Fig. 3, a perspective view of parts of a transverse supporting member employed; Fig. 4, an enlarged sectional View of an elastic cable employed, taken as indicated at line 4 of Fig. l.; Fig. 5, a broken perspective View of a clip employed; Fig. 6, a broken section taken as indicated at line 6 of Fig. l, and Fig. 7 a view of a modified transverse supporting member.

In the construction shown, A represents a frame, B a woven-wire fabric of known construction, and C a fabric-support of improved construction.

The frame in the form shown comprises side members o, end members o', rigidly secured to the side members, and fabric-clamping members o2, joined by spikes o3 and clips ai* to the members o. The clips have nailreceiving perforations, as shown in Fig. 5, and are connected by nails o5 to the ends of the members o a.

The fabric B comprises the usual intertwined longitudinal single spirals Fig. 2, and stronger several-ply spirals b at the longitudinal edges and at suitable intervals between said edges.

The fabric-support C comprises elasticA flexible cables c, having their extremities clamped (with the ends of the fabric) between the members o o2, and a plurality of cross members c' of adjustable length joining the members c at their central portions. narily three of the cross members spaced about ten inches apart, with the central one at Ordithe transverse axis of the bed, are sufficient and desirable. Each elastic cable c preferably comprises an inner comparatively closely wound spiral c2 and a plurality of intertwined spirals c3, sheathing the spiral 02, the whole being strong and resilient, but yielding in a desirable degree. Each cross member c comprises a rod of, provided at its ends with hooks c5, sheet-metal loops c, each formed with a passage c7 for the cable and with superposed legs 08, provided with .perforations c, and clips 01, each embracing an end portionof the rod and the members cS of the corresponding loop c, The clips are shiftable longitudinally of the rods to enable adjustment of the rods to be effected.

In the preferred method of applying the support C the cables c are stretched with small tension beneath the longitudinal margins of the fabric or wire mattress and have their ends clamped between the members o e2 of the frame. The rods c4 are then threaded transversely through the central portion of the fabric, leaving the end portions of the rods unthreaded, as shown in Fig. 2. The loops c are then applied to the cables, the hooks 05 caused to engagev proper perforations in the members es, according to tension desired, and the clips 01 (assumed to be on the rods) slipped into place. Preferably the central member c' is somewhat shorter than the other two members, and in adjusting the tension the cables c are drawn upon at their central portions to form obtuse angles, as shown in Fig. l. The construction results naturally in a slight roll or downward wave of the lateral margins of the fabric, as indicated at d in Fig. 2, enabling the edge of the bed to be used comfortably as a seat.

In the modification shown in Fig. 7 a rod cu serves as a substitute for the transverse member c', said rod ou having at its ends eyes cl2 (one shown) for receiving the cables c. vOne of the eyes of each rod is preparatorily formed or partially formed, and after the rod is threaded through the fabric the other eye is formed about the cable. In this construction the fabric holds the cross members properly spaced under any strain which may be placed upon the structure.

The construction is simple and cheap and IOO each transverse member formed With a Wire.

threaded through the spirals of the fabric, for the purpose set forth.

2. In aspring-botto1n,the combination With a frame and a fabric attached at its ends to the ends of the frame,of a fabric-support,com prising a pair of longitudinal cables beneath the lateral margins of the fabric, and a transverse connecting member connecting and deiecting the central portions of the cables and comprising a rod having hooks at its ends, and loops receiving the cables and provided With perforations receiving said hooks, for the purpose set forth.

3. In aspring-bottom,the combination with a frame and a fabric comprising wire spirals connected with the ends of the frame, of a fabric-support comprising cables arranged beneath the lateral margins of the fabric and joining the ends of the frame, and a plurality of suitably-spaced transverse members joining the intermediate portions of the cables, each transverse member comprising a rod provided at its ends with hooks, loops receiving the cables and provided with a plurality of perforations for receiving said hooks, -for adjustment purposes, and clips connecting the rods and loops adjacent to the hooks, for the purpose set forth.
